INLET AND TRAP FOR SEWERS.

SPECIFICATION forming part of Letters Patent No. 242,329, dated May 31, I881.

' Application filed February .26, 1881. (No model.)

To all whom it may concern:

Be it known that I, ARTHUR J. KELLY, a citizen of the United States,resident at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in lnlets and Traps for Sewers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification, in which Figure 1 is a representation of a side view of my invention, and Fig. 2, is a vertical section thereof.

This invention relates to improvements in sewer traps and inlets.

The invention consists in the construction hereinafter described, and particularly pointed out in the claim.

In the drawings hereto annexed, A represents the roadway having the ordinary pitch to the gutter B, as shown.

C is the sewer-camand D is the cover to the man-hole.

E is the opening for the water to drain through. At the bottom is theplate F. Running from the plate F to cap 0 is the grating G, composed of bars. This plate F has the curved form shown, and the grating takes this turn. The bars Gr run backward in a slant and have the pitch shown, which raises the rubbish to the top and better enables the water to pass into the receiver.

H is the receiver for the water, made of brick-work, and I is the outlet-pipe connected with the sewer.

At K, the top of the opening L of the outlet I, is secured a plate, M, having lugs m, with perforations a a, said lugs extending out into the receiver or trap, as shown. Hung upon these lugs by eyes a a is a cover or apron, N, the edge I) of which projects below the lower face, 0, of the outlet I.

d designates wedges, preferablyof wood, for securing the plate or apron N in place upon the lugs m.

B B are inclined flanged metal pieces at the ends of plate F for the curb to abut against.

By reason of the fact that the plate or apron N, when not inverted,extends below the lower face, 0, of the outlet I, a water-seal is formed in the receiver H, which prevents the gases in the sewer from escaping into the receiver and thence to the air. In cases, however, where the sewer trap or inlet is used in localities where the road-bed is not maeadamized or paved, the plate N should be inverted by removing the wedges and turning the plate up against the plate F and again replacing the wedges d. This is necessary in order to permit the trash to pass off through the outlet I. In such instances the escape of sewer-gas cannot be prevented.

What I claim is-- In an inlet or trap for sewers, the combination, with theplatc M, havingthe in \vardly-projecting perforated lugs m a, of the removable plate or apron N, adapted to extend below the lowerfacc of the outlet I, and the wedges (l, for securing the plate N to place, subs antially as and for the purposes set forth. I

In testimony whereof I affix my signature in presence of two witnesses.

ARTHUR J. KELLY.
